When Creative Cloud was launched in June 2013, we added support for HTML5-based panels in several Adobe products. These new panels open up the world of panel development to a wider range of developers who may be more comfortable working with HTML/JavaScript and CSS. Since June, support for HTML5-based panels has been added to more Adobe products. As of now Photoshop CC, Illustrator CC, Premiere Pro CC and Prelude CC support HTML5-based panels.

Starting in the middle of 2014 we will begin removing Flash-based extension support in Creative Cloud products, starting with Photoshop CC. We encourage all developers to start planning and migrating to the new extensibility framework based on HTML5.

HTML5-based panels allow developers to leverage the rich ecosystem of existing JavaScript frameworks and tools when creating their panels. HTML5-based panels share the same technology with web applications, which opens up exciting opportunities for integration with web services.
